海工混凝土合成纤维混凝土抗裂技术试验研究

Anticrack Technique Test Research of the Synthetic Fiber Maritime Concrete

根据实际工作中杭州湾大桥对海工耐久性混凝土的抗裂要求,通过在混凝土原材料中添加适当掺量的聚丙烯纤维试配,选择出既能够达到混凝土耐久性要求又可以增强混凝土抗裂性能、具有一定经济效益的海工混凝土。

Aeeording to the antierack demand for the lasting maritime concrete in the actual engineering of Hangzhou-Gulf Bridge, the maritime concrete, which can meet the lasting needs and increase the antierack performance as well as have economic benefit, is selected through the trial proportioning of adding a certain amount of PPF into the concrete raw material.
